Edward (Tom Hiddleston) arrives on a remote island off the English coast, to join his mother (Kate Fahy) and sister (Lydia Leonard) who have organised the family holiday to say goodbye to Edward before he embarks on a year of voluntary service in Africa. Hired cook Rose (Amy Lloyd) and painting teacher Christopher (Christopher Baker) join the family in their rustic cottage and on daytrips around the island. But Edwards father repeatedly fails to join the gathering, instead communicating with his wife and children via a series of increasingly strained phone-calls. His absence serves to bring the familys buried anger and repressed emotions to the surface and underlying tensions are gradually revealed through raw scenes of bitter sibling rivalry and marital disharmony.
